//\///E/v TUR wma Patented Mar. 11, 1930 UNITED STATES PATENT OFFICE JAMES W. NABB, OF, NEWARK, NEW JERSEY, ASSIGNOR TO UNITED SHOE MACHINERY CORPORATION, OFPATERSON, NEW JERSEY,A CORPORATION OF NEW JERSEY SHOE-PRESSING MACHINE i Application led .Tune 12, 1925. Serial No. 36,654.

This invention relates to shoe-pressing machines and is Villustrated as embodied in a sole-laying machine of the type shown in Letters Patent No. 1,549,248, granted on August 11, 1925, upon an application of E. E. l/Vinkley. Machines of this type comprise a solepressing pad and a shoe-supporting jack provided with a heel post having a pin or spindle to enter the thimble of the last of the shoe to be operated on, and a toe post having an upper-engaging member ordinarily com'- prising a roll journaled on the toe post. As heretofore constructed, this roll has been formed of rubber arranged to engage the top of a shoe upper substantially at the toe or between the toe and the instep. The rubber surface of the roll gradually deteriorates in use, becoming rough and uneven, so that eventually it is found desirable to replace the roll in order to avoid marking or indenting the shoe uppers.

I have found that the necessity for such replacement can be largely avoided or greatly postponed by providing the roll with a cover not fastened to it but free to creep thereon as the roll is used, being held in place by frictional contact with the roll. Such a roll may be usefully employed in machines such as sole-pressing machines of the type referred to for a much longer period of time than heretofore without liability of marring shoes or damaging the roll itself.

Preferably the roll-cover is m'ade of soft rubber stretched over the roll, frictional contact between the tensioned cover and the roll being depended upon, as above indicated, to hold the cover in place. As a further advantage, such a cover is readily removable and replaceable, thus further prolonging the useful life of the roll.

Although the present invention is described with particular reference to its utility in sole-pressing machines, since it was in an effort to improve the organization of such machines that the invention-was developed, it should be understood that in various aspects the invention is not so limited, but may be employed to advantage in connection with shoe-engaging or supporting members of machines other than sole-pressing machines.

These and other features of the invention, including certain details of construction and combinations of parts, will be described as embodied in an illustrative machine and pointed out in the appended claims.

In the drawings,

Fig.l 1 is a front elevation showing those partsof the machine which are necessary to an understanding of the present invention.

Fig. 2 is across-section of the toe` roll with its cover.

Fig. 3 is a perspective view of the cover detached.

Fig. 1 shows the upper part of the machine only and reference may be made to the Letters Patent referred to for further details if desired. The machine shown is a twin machine and comprises a frame 10, with vertical rods 12, up and Vdown which sole-pressing pads 14 are simultaneously and oppositely moved by a power mechanism comprising toggle links 16. lIhe upper ends of the rods 12 support depending shoe-supporting jacks 18 having jack-pin posts'20 and toe-roll supporting posts V22. The rolls 24 are mounted at the ends of the posts` 22 and are freely journaled there on horizontaly axes perpendicular to the longitudinal axes of shoes in the machine. The rolls' 24, asV shown, are formed of rubber, for example substantially as shown in United States Letters Patent No. 1,163,589, granted Dec. 7 ,1915, on the applicationof H. A. Davenport. Each roll consists of agmetal sleeve 26, surrounded by a preferably approximately cylindrical body 28 made of rubber, the'exterior portion of which, at least, is rubber of medium hardness.

Each of the illustrated-rolls 24 is provided with a cover or sleeve 30 made of relatively thin soft rubber. For example, I have found that a piece cut from an inner tube of a motorcycle or automobile tire serves well for this purpose, although a satisfactory rubber cover may be obtained in various ways. The cover 30 is slipped over the roll, being preferably of such diameter as to require a little stretching to place Ait in position, and being long enough to cover the length ofv the roll.

The use of this cover avoids damage to the uppers of shoes treated by the machinel Also, the described mounting of the cover allows it to stretch somewhat, which appears to contribute to the usefulness of the cover. The illustrated machine is used in exactly the same manner as the machines disclosed in the Letters Patent referred to, and no detailed exposition of such-use is necessary herein. Y

The rolls above described Vare rolls only in form. They are'really only Contact members or supports, and do not rotate `in any deiinite way during the pressing operation on a shoe. They do move enough so that, in time, they distribute the wear over their whole surfaces, but this movement is adventitious and small or even nothing during anyk fewminute period. The invention should not be understood as limited to a roll, or cylindrical contact member, as it is useful with-contact members of other forms.

Having described my invention, what I claim as new and desire to secure by Letters Patent of the United States is: l. A sole-pressing machine having, in combination, a sole pressing pad, and a shoe upper engaging member provided with a cover arranged to creep on the said member under the pressure of the shoe upper.

2. A sole-pressing machine having, in combination, a sole pressing pad, and a shoe-supporting jack comprising a shoe upper pressing member provided with a relatively thin rubber cover frictional-ly held on the pressing member and arranged to move relatively to the pressing member undery tangential stress.

V 3. In a sole-pressing machine having a sole pressing pad, a shoe-supporting jack comprising a toe post and a roll journaled thereon and provided with a'rubber tube of somewhat smaller normal diameter than the roll stretched over the roll and arranged to engage the upper of a shoe andto creep on the roll under stresses tangential to the roll- 4:. A toe, roll for a sole-pressing machine having apsoft rubber cover stretched over it, and arranged to creep under stresses tangential to the roll.

5. In a machine for operating on boots :and

shoes, a shoe-treating member, and shoe-supporting means comprising a member arranged to engage the top of the forepart'of the shoe and provided with a tensioned cover 'frictionally held in place on said member, while capable of creeping thereon in response to pressure of the shoe against it.

6. In a machine for operating on boots and Y shoes, a shoe-treating member, and shoe-supporting means comprising a member provided with atensioned, relatively thin rubber cover frictionally held in place on said mem ber but free to creep and stretch to 1 avoid marring the shoes treated.V
